DESCRIPTION
The SP6127 is a PWM controlled step down (buck) voltage mode regulator with V
IN
feedforward and
internal Type-II compensation. It operates from 4.5V to 29V V
IN
, making it suitable for 5V, 12V and 24V
applications. By using a PMOS driver, this device is capable of operating at 100% duty cycle. The high-
side driver is designed to drive the gate 5V below V
IN
. The programmable overcurrent protection is
based on the high-side MOSFET’s ON resistance sensing and allows setting the overcurrent protection
value up to 300mV threshold (measured between VIN-LX). The SP6127 is available in a space-saving 6-
pin TSOT package making it the smallest controller available capable of operating from 24VDC supplies.
